Windbreakers have never gone out of style. They pair perfectly with almost anything, are lightweight, form fitting and feel great.

True to the era, these are made with 100% Nylon which means they do not have any stretch in them (don't try to squat a PR in them). However they are water resistant, made with an ultra cool reflective material and pair perfectly with our Limited Edition Windbreaker Jacket. 

In general the recommendation is the following:

Whatever pants size you typically wear, go with that size. If you normally wear medium, wear medium. Large go with large etc. We'll be uploading a size chart in a day.
